Abstract

The purpose of this study was to investigate metacomprehension (MetaC) in adults with aphasia by examining its linguistic and non-linguistic contributions. Adults with aphasia listened to narratives and made judgments about the accuracy of their answers to yes/no questions. Several linguistic and non-linguistic tests were administered and a correlation matrix revealed multiple significant associations. Thus, data were reduced using factor analysis. Two non-linguistic factors (perseveration and switching) and one linguistic factor (aphasia/comprehension) emerged. Regression analysis revealed that these three factors explained 57% of the MetaC variance, more than what was explained by any one factor alone.
